Blew the capacitor on my analytical balance scale using the wrong power adapter. I need help finding a replacement compatible capacitor to buy. Will any 100uf 40v capacitor work as a replacement?

You can get the capacitor from anywhere, like Digikey, Mouser etc. 100µf 50 v 105° are very common Hope nothing else got damaged like that IC.
Just measure the size to get one that will fit.
The ic seems to be a LT1172cs8Last edited by R_J; 12-28-2024, 11:45 AM. -
cool thanks. ill get the 100µf 40 v 105° from digikey. Can you tell me why you recommend a 100µf 50 v 105° instead of a 100µf 40v capacitor? For the ic how did you come with the LT1172cs8 model? It does have the same dimensions as the one on my board. What does the 940 numbers mean on this ic? if the smd components further down the pcb board from the blown capacitor have continuity starting from the power input to those components does that mean they are not shorted or blown including this ic?Comment

there are standard values and unusual ones.
standard ones include 35v and 50v, 40v is going to be harder to find.
50v is better anyway because it's the maximum so you get more headroom with a 50v part.
try using panasonic FR series.

The IC was probably damaged too so if you haven't already made an order I would add it as well.
(The reasoning being it is rated for 40v input just like the capacitor so if the capacitor failed the IC very likely did too)."The one who says it cannot be done should never interrupt the one who is doing it."Comment

Thanks for the help everyone. An update on this, Ive replaced the capacitor with one of these panasonic 100 µF 50 V and the scale didnt turn on. 😐Ill be ordering the ic and testing that out next. https://www.digikey.com/en/products/...FC1H101/266332Comment

It was the switch regulator chip. I replaced the chip and now the scale worksComment

Hi there, looking for a compatible replacement for a diode type labelled "V6 18" from a dead Panasonic plasma TV power source. Possibly a V6 600 volts diode as seen here: https://electronics.stackexchange.co...nt-diode-v6-88 ?
Thank you

I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before... -
Capacitor has been discontinued (EGXF101ELL331MM20S) all of the replacements I have found have are smaller than 0.709" Dia (18.00mm). I would like to use the same size or at least close to the same size Capacitor. 19mm would be too big as they would touch and not be able to through hole mount. Tia...

Hi, I'm super new to this capacitor stuff but I've some basic soldering experience with old cellphones PCBs and headphones. I have this APAQ AR5K 820∆μF 3V Dc Capacitor from a motherboard that I'm looking to replace, photos I've attached. But I'm unable to find a 3V one like I've marked in the spec sheet in red (This is the one currently present in the motherboard). But the 6.3V one I can find (marked in blue) is of similar dimensions but different specs as mentioned in the table. Is it okay to replace it with higher voltage cap, slightly higher ESR, slightly lower ripple current, and double... -
I have a damaged capacitor from a bootleg double dragon arcade pcb and I have the normal values from it:
10 volt, 100uF, 85c, but someone from an arcade forum said that the ripple current is not that critical and any good quality low esr cap would be fine, the damaged one is an electrolytic can type but I don't know what to look for as far as low esr is concerned, can a ceramic capacitor be used instead, the capacitor is going to the +5 volt
I don't know the brand but on the top of the capacitor is stamped "76 F6" if there is a datasheet ide be able to...
